^yeah AMR runs in an old warehouse here and the units are positioned/patrolling through out the city.
Also wondered why LAPD has there own dive team rather then relying on LAFD?
To Quote Brian humphrey:
"LAFD Firefighter/Divers are assigned full-time to three of our five fireboats.
There are a total of eight divers on-duty at all times at the Los Angeles Fire Department. There are two assigned to each of the three small fireboats (Boats 1,3,5) mentioned above, and one backup diver each at the Fire Stations that house the larger fireboats (Boats 2 and 4). "
My assumption is LAFD divers are very busy, plus LAPD divers undergo special port security training etc., Also I assume from this that UDU is probably the unit called to emergency dive situations off major waterways.
*According to an article I just read, LAFD divers are brought to scenes off via helicopter for off the coast/harbor water rescues, stills seems to me UDU could prove faster,and have more equipment.*
